Agility 50 / Kymco Agility RS 2013 CK50QT-K Start up/Speed problems
« on: March 30, 2019, 12:42:00 PM »
New to forums long post but I want to give as much information as I can
I have a kymco agility rs 2013 I believe but this is just going off the REG PY13 (first reg 28-08-2013)
Type CK50QT-5
Version CK50QT-5D
When starting up it electrically (kick-start broken) it can take a few attempts 3-5 starter motor is functioning or at least not 100% dead.
When the engine starts I will try rev (twist the throttle?) and it can not respond so will twist forward and backwards in a cycle this will sometimes keep the engine from cutting out.
The more I do this the engine will start to gain momentum and I will start reving just by holding the throttle? In place Without having to twist it back and forth.
once ive got the bike able to move I will try reach top speed about 33mph according to the speedomitor but it will stay at around 20-23 for about 2-3 mins I can reach my 30-33 on even ground after the engine has gone for a bit
Once this happens the engine can sometimes still cut out in a couple of seconds of no revs so at traffic lights im always having to keep a small rev going to stop a cut out
If I go up a hill speed will drop at best 15-21mph at worste 5-10 I can even have it slowly stop no movement and the engine will cut out and have to restart the engine
i have had work done on the bike and had a destricted CDI put into the bike this made the bike accelerate slower speeds of 40-45 were achieved but made the bike slower up hills 20-25 this gradualy got worse and the old cdi was put back in, rollers were replaced and carb was cleaned out
Another attempt was made with a different destricted CDI box because it was believed it could have been faulty a different box was put in and the same problem happend again I was assured this was the correct CDI as he said the connecter (plug socket so to speak?) was unique to this bike
Same story again old cdi unit was put back in place and the bike was working again however some of the power was lost and the bike has gradualy got worse im concerned im going to do damage to the bike if I keep driving it
Things I have thought that could be wrong are
Spark plug?
Rollers?
Carb dirty?
CDI box failed?
Starter motor?
Battery?
Pistons?
I just want some advice i know there are YouTube videos with guides i want to try fix it my self but dont want to be replacing parts that are working fine thinking there broken if anyone has any advice about what i should do first i would appreciate it taking it back to the mechanic is also an option
